This -inventionrelates to reservoir pens, and has forits objectto provide a reservoir pen nib simple in constructionv and efficient in use. i

"5 The invention consists in the provision in n10 Vof al plurality of longitudinally extending Vfins orv webs. Y

Preferably two such kfins or webs are' provided spaced apart and parallel or substan- 1 tially parallel with*V each l other, one "being 15 located on eachk side of the slit and/ or piercing on the middle lineof'the nib. The rear ends 'ofthe saidiinsjor' :webs maybe in line with the posterior end ofthe middle slitl and/or piercing o f the'nib or they mayterminate at 'terior endof theslit-and/or piercing as'may be desired. l

" The webs'or fins maybe obtained by stamp'-y ing and bending operationsfrom a blank of "9325 thin sheet metland are providedl atyfthe "posterior ends thereofwith means whereby they are securely attached -to the body of the nib. Y

The inveiaienwiu be ffufher described 'WGQwith reference to the accompanying drawings, wherein z'-` i,

FigureS -is asimilar view to Figure 1 of a modified construction of` reservoir fitment hereinafter more-particularly referred to. Y

Figure 9 ris'across section onl tlieplane indicated by the dotted line 9 9, Figure 8;

Figure 10 represents in plan the blank from which the said modified reservoir fltment is obtained, and f Y* f Figure 11 shows the modified reservoir iitmentA detached inside elevation; i, The saine numerals of reference indicate part-having as usual the'middleslit and/or lpiercingw12". On the lower or `underside of Jthe saidv anterior portion 12 and disposed 'preferably symmetrically one on each side ofthe middle slit or piercing 12b-are the longitudinallyextending fins or webs 13, the said 7 vfins or websbeinginthe main parallel or substantially parallel." The upper edges o fthe lfins lor webs 13 that is to say the edges which arepiesented tothe underside of the anterior part 12'of the nib lie flush or practically flush therewith and preferably the said ledges vare yinterconnected'by a transverse web, or webs,

513 vformed integral therewith and serving to n preserve the interconnected edges at ythe dei -sired distance apart and give rigidity thereto,

but' ifdesired suchinterconnecting web or websmaybe' dispensed with. e 4 i webs 13 I takey ablank of sheet metal of suitable contour and dimensions, as for example, the contour represented in Figure 5, the said blankbeing pro-y vided either in the stamping `operation whereby it is obtained, or by a subsequent operation, lwith the slots or apertures 13b, 13c and 13d leaving the parts 13aL toform theinterconnecting webs hereinbefore referred to. I. The blank Figure 5 terminatesatone end i vin an unslottedpart 13 having laterallyeX- ktending-ear piecesor wings 13t which serveas hereinafter described in the attachment of the ins to the pen nib.

By a suitable pressing or bending opera.- tion or operations the parts of the blank on either side of the slotted middle part are brought into vertical or substantially vertical planes so as to lie parallel or substantially parallel with each other, as best seen in Figure 3, and the adjoining unslotted part 13c is given a configuration the counterpart of that portion of the nib against which it fits when the blank is applied to the underside of the nib with the fins or webs 13 disposed in the desired position relative to the anterior portion 12 of the nib and the middle longitudinal slit and/or perforation 12b therein. At the same time the ear pieces or wings 13f are or may be bent to the position in which they are represented in Figures 6 and 7, so as thereby to form clip-like parts adapted when the iin orweb forming blank is applied to the nib to grip and overlap the adjacent parts thereof as is best seen in the section Figure 4.

The front ends of the wings 13 are or may bedmade divergent as shown in Figures 1 an l.

The edges of the nib at the parts which when the fin or web forming blank is applied thereto are overlapped by the said ear pieces or wings 13 are formed with slight recesses or depressions which provide shoulders or abutments 12C and 12d (see Figure 2) serving definitely to locate the ear pieces on the nib body and prevent longitudinal displacement of the webs or fins 13 in a rearward direction or, if desired, in either vdirection. The prevention of forward motion however and the very secure retention of the web or fin blank in place is ensured providing the body of the nib with a tongue-like part 12e which, by a suitable slitting and pressing operation, is depressed therefrom into such location on the underside or face of the nib that it can engage below the underside of the fin or web blank preferably at or about thepart thereof at which the posterior ends of the fins or webs adjoin the extension 13e on which the ear piecesor wings 13f which clip the respective sides of the nibs are provided. The tongue-like part 12? is so depressed from the body as to form a sharp shoulder 12f (see Figure 2) at its junction therewith, which shoulder forms 'a definite abut-ment for the edge of the fin blank which is presented thereto when the said blank is properly positioned on the nib,

.the shoulder serving definitely to locate the position of the tin or web blank. The front or free end of the tongue-like part is slightly bent or turned down to provide a lip which `guides the web or iin blank into its engaging position with the tongue member, the fin or web blank being suitably slotted to permit -the tongue 12e to pass therethrough and engage below the same.V lVhen this engagement has been effected and the iin blank pushed against the shoulder 12f of the tongue the rear part of the iin blank engages with the shoulders 12C and 12d formed by the slight recesses or depressions in the sides of the nib and the iin or web blank is very effectively restrained from longitudinal motion in either direction. j

Further, the engagement of the tongue member 12e below the lower face of the web or fin blank serves to clip'the said blank closely against the underside of the nib and retain the edges of the webs or ins which are presented to the underside of the nib in close contact therewith.

I wish it to be understood thatl do not limit myself to any particular shape or con tour of the nib body nor to the precise construction of the parts described as the same may be varied without departing from the invention, for example, the webs 13 instead vof being of substantially the same depth from front to back as shown may vary in depth from front to back the ends thereof adj ac'ent the point of the nib rising from the nib without the formation of a definite shoulder or front edge.

Further, if desired the longitudinal edgesv of the webs or fins 13 may be furnished, as is shown in Figure 8, with ear piecesor wingsv 13g formed on the longitudinal edges thereof remote from the underside or face of the 'nib and bent laterally outward, that is to say, in a direction toward the respective sides of the nib, the said ear pieces or wings being preferably disposed at or adjacent the posterior ends of the fins or webs 13.

A cross section of 'this modification on the plane indicated by the dotted line 9-9, Figure 8, is shown in Figure 9. Y

Figure 10 shows the blank from which the said modified iitment is formed and Figure 11 is a side elevation of the said fitment detached from the body of the nib.

By the improvements described a resere voir pen nib simple in construction and very efficient in use is provided, and further the three point attachment of the web or fin blank to the nib, constituted by its engagement with the depressed tongue 12e and of itsl wings 13gv with the edges of the nib serves very effectually to retain the webs orfins in the desired position relative'to the nib.

What I claim is A reservoir pen nib comprising a separate member adapted to be disposed on the underside of the anterior portion of the nib, a plurality of substantially parallel webs formed integral with thesaid member and constituted by slitting the said member and bendl 'ing the marginal portions of the slit sections through angles of approximately 90 so that the webs are arranged edgewise relatively to ioo the nib and with their upper edges in sub- Vstantial abutment with the underside of the l anterior portion of the pen nib, transverse means located intermediate the ends vof the webs and connecting the outer edges thereof,

a rear extension of the said member shaped e to conform to the part of the nib to which it e isadjacent, a cut away portion adjacent to the said shaped rear portion of the aforesaid n member, a centrally disposed downwardly bent tongue pressed out of the nib and adapted to engage with the said out away portion',

and ear pieces formed integral with the said rearward extension and adaptedV to be bent round the nib for securing the aforesaid member thereto, said ear pieces in conjunction with the aforesaid tongue constituting a three point attachment means for the said member which ensures the correct Apositioning thereof relatively to the nib.

In testimony whereof I have sig'nedrnny name to this specification. Y
